London bomb threat: Police officers patrol the perimeter of Buckingham Palace in London, Monday. Irish militants opposed to the peace process with Britain warned of a bomb in central London on Monday, a day before Queen Elizabeth makes a historic visit to Ireland.

Police said earlier that a security alert had led to the closure of the Mall, a broad avenue leading to Buckingham Palace, Queen Elizabeth's residence, but refused to say what had prompted it.

Despite a 1998 peace deal mostly ending Northern Ireland's three decades of conflict, violence by dissident Republicans opposed to the peace process has been increasing in the British-ruled province.

A Northern Irish republican militant group, the Real IRA, told Queen Elizabeth, head of state of Ireland's former colonial master, last month she was not welcome on Irish soil.

'REAL IRA'

British member of parliament Patrick Mercer said last year he believed militants from Northern Ireland hoped to stage attacks on the British "mainland".

The last Irish-related attack in London came in March 2001 when a powerful car bomb exploded outside the BBC's London headquarters. Police say the Real IRA, a republican splinter group opposed to the IRA's ceasefire, was behind the blast. One man was wounded.

The IRA mounted several bombing operations in England during its campaign. Such attacks were more difficult than actions in northern Ireland, since the guerrillas lacked support networks; but they arguably had more impact on the British government.

The IRA staged its most spectacular attack in 1984 when it blew up the Brighton hotel where Prime Minister Margaret Thatcher was staying, along with her chief ministers. She narrowly escaped, but five people were killed.

Britain's interior ministry said in a statement: "We face a real and serious threat from terrorism ... There is a continuing need for vigilance and the public should report any suspicious activity to the police."

The police said the threat of Irish-related attacks was considered lower than the overall threat to Britain from international terrorism which remains at severe, the second highest level on a five-step scale.
